SPEEDER FOB RQ'VING GOTTIGN.

Specification of Letters Patent No. 724, dated May 4, 1838.

To-all tub-m it may concern:

Be it known that I, WILLIAM MASON, of Taunton, in the county of Bristol and State of Massachusetts, have made certain Im-j provemen-"ts in what I denominate the Horizontal Spindle-Compressing Speeder, and

I do hereby declare that the following is a which slides in the groove in the spindle,so that both are compelled to turn together.

full and exact description thereof.

In order to make my improvements fully known, and to show what I deem a convenient manner of connecting them with thel other parts of the speeder, it will be necessary for me to ,give a general arrangement of the moving parts of the machine, al-l though I do not make any claim thereto; nor do I intend thereby to limit myselfto such an arrangement, but to employ any other which is compatible with the improvements which I have made. I

In the accompanying drawings Figure 1.

represents a back view of a portion of the machine, a, a, a, bein the heads of the spindles to be presenfiy described. The

drum, cones, pulleys, and general gearing not presenting anything peculiar I do not describe. Fig. 2. is an end view thereof, Fig. 3. a vertical section passing through one of the spindles, and its appendages, and Fig. 4. atop view. I

In each of the figures those parts which correspond are designated by the same lets ters of reference.

I place the spindles a, b, horizontally, and instead of the ordinary flyer I employ one which is cylindrical; this cylindrical part is shown at 0, c, it is made of tin plate, or any other metal; at one end it is soldered to a pulley d, cl, and at the other to a hoop, or ring 6, e, which gives it a smooth and proper finish. The pulley d, d, is so formed as at the same time to constitute one end of the cylindrical flyer and to receive the tube or bearing which constitutes its support, and also that of one end of the spindle.

The pulley z', '5, serves to drive the spindle, and this pulley is attached to a hub j, j, which is hollow, and allows the spindle to pass through it, while it can be drawn out 0 for dofiing, without disturbing the pulley.

To secure the spindle when in its place, it has a small pin projecting from it which passes into a notch or slot in the hub in the form of the letter L, the pin and notch operating like a bayonet look, as shown sepa* rately at 7', Fig. 2. There is a groove made along each spindle, as shown by the double lines, and a pin, or feather, projecting inward on the bore of the pulley i, i, enters this groove, thus connecting,land causing them to revolve together, but allowing'the spindle to be drawn out readily. A sliding collar 2; fits on to the spindle and has, like the whirl z, a feather or pin in its interior,

This collar has a clutch, or bayonet look by which it-is attached to the spool, in the same way in which the spindle and the hub j, are

from the spool, and in Fig. 3. as attached to it, h, h, being-the spool and covering. The

wheels of the wave rail, which governs the traversing motion of the spools are shown at f, f, Figs. 2 and 4. These have grooves onthem adapted to suitable ways; m, m, Fig. l. is the wave rail, extending from end to end of the machine; To this wave rail the proper mot-ion is communicated by means of a rack and pinion, seen at k, is, Figs. 2 and 3. The action of this part of the apparatus does not differ from that in other machines for the same purpose.

The relative motions of the fiyer, and of the spindle with'its spool, which. must be such that the spindle will run as much faster than the flyer as is necessary to take up the roving properly, and which has to be de-;

attached; this is to cause the spool to travcreased as the quantity of roving increases, a

is elfected by the well known dilferential be superfluous to describe. V pp The means of communicating motion to the drawing rollers, 0, 0, and to the other operative parts of the machine make no part of my invention, being the same withthose in general use.

To enable the wave rail to cause the spools to traverse, and at the same time to allow the spool to be readily changed the pieces of metal 27, p, are attached to the wave rail, by joint pins, as seen atq, Fig. 3; when turned up they take intoa groove on the collars, 9, but when turned down they are disengaged from it. fiyers through which the roving passes from the drawing rollers are in the centers of the front bearing of the flyers, 1', 1', 'r, at this end the flyer is sustained by and revolves in the bar or plate, 8, 8, the roving passes through the holes 1", 'r', and out at the back end of this fiyer at, t, and is conducted by asmall tube or channel u, u, into and through the flyer to its back end, to be laid upon the spool; the part of this tube, a, is on the interior of the spool, the other part Within it.

The rounded end '0, o, of the flyer not only forms the tube, or perforated, bearing 7*, upon which it revolves, but also forms the support of one end of the spindle as before noticed, and as distinctly seen in the section, Fig. 3. The opposite end of the fiyer, which is open, and is surrounded by the hoopior wing e, e, is supported by,'and revolves upon a semicircular ring, or bearing, w, w, attached to a standard w. The semicircle to,

'may be. replaced by friction rollers if preferred, V

- The most important part of my improvev ment is that which I am now about to describe, and thisconsists inthe employment of what I have denominated centrifugal levers, of which I usually adopt two to each fiyer, attaching them by screws, orjoint pins to the face of the hoop, e, e, on the back end of the fiyer, allowing them to turn freely on e, e, constituting the open end of the flyer, to which they are afiixed, the inner or small end of one of these centrifugal levers receives'the thread in a hole, or loop, made in it for that purpose,as it proceeds from the small tube by which it iscarried through the flycr. This loop, or opening, being seen at which gives a separate view of one of the levers. their outer end, 2, z, they'eXpand by their centrifugal force, with a power proportioned to their velocity, causing their inner ends to press upon the spools,'laying the yarn very hard and compact. Bythis construction a very high speed may be advantageously given to this instrument.

All that I claim as new, and wish tosecur by Letters Patent is, g

1. In manner of connecting the grooved spindle with the pulley z, and with its hub, and with the fiyers, so that it can be drawn out for dofling, as herein fully shown.

2."The construction and employment of These levers being heaviest at the centrifugal levers, made and operating in the way above described.
